| 摘要: | In the Anthropocene epoch, understanding the impacts of anthropogenic influence on biodiversity and behavior of vulnerable wildlife communities is increasingly relevant to effective conservation. However, comparative studies aimed at disentangling the concurrent effect of different types of human disturbance on multifaceted biodiversity and on activity patterns of mammals are surprisingly rare. We applied a multi-region community model to separately estimate the effects of cumulative human modification (settlement, agriculture, and transportation etc.) and human presence (aggregated presence of dogs, people and livestock on camera) on species richness and functional composition of medium- and large-bodied mammals based on camera trap data collected across 45 subtropical montane forests. We divided the detected mammal species into three trophic guilds: carnivores, herbivores and omnivores and assessed the nocturnal shifts of each guild in response to anthropogenic activities. Our results suggest that human modification and human presence had differing effects on mammals. Overall species richness tended to increase with human modification but decrease with human presence. Human modification was associated with significantly lower functional diversity, community average body mass and proportion of carnivores. Human presence was associated with a strongly reduced proportion of herbivores. The proportion of omnivores significantly increased with both habitat modification and human presence. In terms of activity patterns, omnivores and carnivores became more nocturnal in response to human modification. Our results demonstrate that anthropogenic disturbances can lead to drastic loss of functional diversity and result in a shift to nocturnal behavior of mammals. Conservation planning should consider concurrent effects of different types of human disturbance on wildlife communities, and take into account not only species richness, but also functional diversity and animal behavior. |
